Overview

Cboe has received approval to amend its rules for Cboe Options Exchange (C1) to expand trading hours for designated multi-listed equity options. The changes involve the addition of an early morning Global Trading Hours (GTH) session and an after-market Curb session. Cboe's rule change reflects the following trading sessions for select multi-listed equity options meeting certain criteria:

  • Begin Order Acceptance: 7:15 a.m.
  • Morning session (GTH): 7:30 a.m. – 9:25 a.m. ET
  • Afternoon session (Curb): 4:00 p.m. – 4:15 p.m. ET
Pursuant to Cboe's criteria, select equity options are eligible to trade during the new sessions if:

  • the option class has an average daily volume of 150,000 contracts or higher,

  • the underlying equity to the option has a $50 billion or higher market capitalization, and

  • the underlying equity to the option has an average daily traded volume of 10 million shares or higher.

The rule change permits Cboe to select up to 100 equity option classes meeting this criteria for trading during the new morning GTH session and the afternoon Curb session.
